That is a (mis)feature of MySQL itself, not of the InnoDB storage engine
if used in a mixed table type query by MySQL. InnoDB does not control
what is done in the "upper management" with the rows it returns from a
scan. This kind of abuse is as much InnoDB's fault as it is your fault
when your quite accurate work is merge-joined with marketing material
for decision making.
